electrophiles are the electron deficient species whereas nucleophiles are the electron rich specie .the other difference is that electrophiles are the electron loving species and nucleophile are electron hating.
Andrew Keith Pover has written: 'Reactions of 1,3-dilithioacetylides with electrophiles'
Lewis acids help in the generation of electrophiles in Friedel Crafts reactions.
depending upon the reaction conditions halogens act as electrophiles,nucleophiles and freeradicals
An electrophile is any an agent that is attracted to electrons. The electrophiles stimulate a chemical reaction by bonding with a nucleophile, creating an electron pair.
because it attains a positive charge because of the higher valency. such molecules r not electrophiles.....
CH3+ , NO2+ , Cl+ and other positive species except metallic ions, NH4+ and H+ ions.
Electrophiles and Nucleophiles are atoms, bonds, or (small or small parts of) compounds that are involved in chemical reactions.Nucleophiles are "nucleus loving" which means that they want to give up electrons and gain a bond with another atom. These are usually negative or neutral compounds. (-OH base is a good example, the oxygen usually gives electrons)Electrophiles are the opposite, they are "electron loving" which means that they gain electrons (from the nucleophile to form a new bond). (A carbon-carbon double bond or hydrogen molecule can act as an electrophile for example.)
Alcohols are versatile in nature because it can react both as electrophiles and nucleophiles according to the cleavage of bonds between them(i.e. O-H or C-O bond).
electrophilic addition reaction
The positive species which may attack on carbon or a pi bonds are electrophile as Cl+, NO2+ etc. but H+ and Positive metallic ions are not electrophile .
quick answer is that nucleophiles like positive areas of molecules and electrophiles like negative areas of a molecule. In methane (CH4) the hydrogen and carbon have similar electronegativities and therefore there are no real positive and negative centres. Hope this helps mate
